Chrysanthemum plant named ‘Yellow Passadena Jogger’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yellow Passadena Jogger’, characterized by its uniform, upright, outwardly spreading and rounded plant habit; moderately vigorous growth habit; freely branching habit; dense and full plant habit; freely flowering habit; decorative-type inflorescences with bright yellow-colored ray florets; long flowering period; and excellent garden performance.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘YELLOW PASSADENA JOGGER’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum×morifolium andhereinafter referred to by the name ‘Yellow Passadena Jogger’.

The new Chrysanthemum plant is a naturally-occurring whole plantmutation of Chrysanthemum×morifolium ‘Passadena Jogger’, not patented.The new Chrysanthemum plant was discovered and selected by the Inventoras a flowering plant from within a population of plants of ‘PassadenaJogger’ in a controlled greenhouse environment in Staden-Oostnieuwkerke,Belgium in October, 2008.

Asexual reproduction of the new Chrysanthemum plant by vegetativecuttings was first conducted in a controlled greenhouse environment inStaden-Oostnieuwkerke, Belgium in March, 2009. Asexual reproduction bycuttings has shown that the unique features of this new Chrysanthemumplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under allpossible environmental conditions and cultural conditions. The phenotypemay vary somewhat with variations in environment such as temperature,daylength and light intensity, without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Yellow Passadena Jogger’. Thesecharacteristics in combination distinguish ‘Yellow Passadena Jogger’ asa new and distinct Chrysanthemum plant:

-   -   1. Uniform, upright, outwardly spreading and rounded plant        habit; moderately vigorous growth habit.    -   2. Freely branching habit; dense and full plant habit.    -   3. Freely flowering habit.    -   4. Decorative-type inflorescences with bright yellow-colored ray        florets.    -   5. Long flowering period.    -   6. Excellent garden performance.

Plants of the new Chrysanthemum differ primarily from the mutationparent, ‘Passadena Jogger’, in ray floret color as plants of ‘PassadenaJogger’ have greyed yellow-colored ray florets.

Plants of the new Chrysanthemum can also be compared to plants ofChrysanthemum×morifolium ‘Tardel’, not patented. In side-by-sidecomparisons conducted in Staden-Oostnieuwkerke, Belgium, plants of thenew Chrysanthemum differed from plants of ‘Tardel’ in the followingcharacteristics:

-   -   1. Plants of the new Chrysanthemum flowered earlier than plants        of ‘Tardel’.    -   2. Plants of the new Chrysanthemum had decorative type        inflorescences whereas plants of ‘Tardel’ had diays type        inflorescences.    -   3. Plants of the new Chrysanthemum were not susceptible to Rust        pathogens whereas plants of ‘Tardel’ were susceptible to Rust        pathogens.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of thenew Chrysanthemum plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Chrysanthemum plant. The photograph on the first sheet comprisesa side perspective view of a typical flowering plant of ‘YellowPassadena Jogger’ grown in a container. The photograph on the secondsheet are close-up views of the upper and lower surfaces of typicalinflorescences (left) of ‘Yellow Passadena Jogger’ and upper and lowersurfaces of typical leaves (right) of ‘Yellow Passadena Jogger’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown during the summer and autumn in 19-cmcontainers in an outdoor nursery in Staden-Oostnieuwkerke, Belgium andunder conditions and practices which approximate those generally used incommercial Chrysanthemum production. During the production of theplants, day temperatures ranged from 10° C. to 25° C. and nighttemperatures ranged from 5° C. to 15° C. Plants were 5.5 months old whenthe photographs and description were taken. In the followingdescription, color references are made to The Royal HorticulturalSociety Colour Chart, 2007 Edition, except where general terms ofordinary dictionary significance are used.
